DOOR-FASTENER.

Specification of Letters Patent.

Application filed October 12, 1909.

Serial No. 522,303.

To all whom it may concern:

Be it known that I, ALFRED SHEDLOGK, a Citizen of the United States, anda resident of Cannon Station, State of Connecticut, have inventedImprovements in Door-Fasteners, of which the following is aspecification.

The object of the door fastener and guard forming the subject of thisinvention is to provide a simple and effective means for holding a doorsecurely closed and adapted to hold the door in partly open position,the construction and arrangement of the parts being such that themovable bar member, attached to the door jamb, upon being released fromits holding catch, attached to the door, may be passed into the guarddevice for holding the door partly open or be moved away from the doorto permit the door to be fully opened.

In the accompanying drawings :Figure 1 illustrates, in elevation, anembodiment of the invention acting as a door fastener or bolt; Fig. 2 isa similar View showing the device as a guard, holding the door partlyopen; Fig. 3 is a plan view of Fig. 2; Fig. 4 is a view similar to Fig.1, showing the device with modifications applied to a door reverselyhung to that shown in Fig. 1; Fig. 5 is a plan view of Fig. 4i, and Fig.6 shows, in elevation, the device with other modifications.

As shown in the drawings this door fastener and guard consists of threeparts which may be cast or otherwise formed in the de sired shapes andapplied to use without any tooling. The movable locking part consists ofa plain bar a provided at one end with a head engaged by a socket pieceI), which by means of screws is secured to the door jamb c. In Figs. 1,2 and 3 the head d is spherical and seats in a correspondingly shapedrecess in the socket piece 5 so as to constitute a universal connectionof the bar a with the door jamb, the parts being so made that the barwill hang vertically against the jamb when not in use. In the otherviews of the drawings the head of the bar a is transversely arranged, asa T head 6 and the sockets f are provided with rectangular recesses inwhich the T heads are free to slide and turn. All of the sockets haveslots or openings in their front sides through which the bars extend andthrough which the heads d and 6 cannot pass. The other part of thedevice comprises a plate 9, secured to the door it, by screws, anupwardly extending hook or catch 2' behind which the bar a: is passed tolock the door closed, as shown in Figs. 1, 4C, 5 and 6, and a guard armj above the hook or catch 2' behind which the bar a is passed when thedoor is to be held partly open, the bar a being provided with a lug 7a,which, by contacting with the edge of the plate 9, limits the distancethe door can be opened, as clearly shown in Fig. 3; and to prevent thedoor closing, when so held partly open, a notch or recess Z formed inthe Side of and near or at the end of the bar a engages with aprojection at extending inwardly from the arm j. This projection m is soformed and bears such relation to the hook or catch 71, as regardsposition, that there is just suflicient space between it and the plate,gfor the bar to pass behind the arm, and the opening between it and thehook or catch 2' is sufficient for the passage of the bar a in itslateral movements toward and from the door.

Figs. 4 and 5 besides illustrating the square socket and T headmodification show a notch 11. in the upper edge of the bar a which hasto aline with a lug 0 extending downwardly from the projection m of thearm y before the bar a can be moved laterally away from the part of thedevice attached to the door, and before this alinement can take placethe bar a has to be longitudinally moved to bring its T head (2 towardthe rear part of therectangular recess in the socket f. Now in placingthe bar against the plate g so that it may be passed behind the guardarm y, it is, during its upward movement pushed forward by a lug p onthe bar riding along an inclined projection g on the socket, thusthrowing the notch n out of alinement with the lug 0, so that when thedoor is closed with thebar a behind the arm j, the bar falls down behindthe hook or catch 2', as shown at Fig. 4L, and the bar has to be moved1011- gitudinally as well as laterally to be released entirely from theholding part of the device 3 attached to the door. The guard arm 9' withits projection we may extend upwardly, as shown at Fig. 6, as anextension of the hook z, and will in this position perform the samefunction with the bar a as in the position it occupies in the otherviews; but in this case the bar in being moved away from the door willpass directly upward out of the guard arm j, and to make said releasingmoveineiit of the bar more complex, a notch 1 in the edge of the bar hasto pass over a lug 8 located on the plate 9, and this can only occurwhen the bar is longitudinally moved to bring its T head in forwardposition in the rectangular recess of the socket, as shown by the dottedlines w. From this upper position of the bar a, as it is moveddownwardly behind the hook or catch 2', a ledge 23 on the bar actsagainst the edge of the arm j and so longitudinally moves the bar tobring its T head in rearward position in the socket and so throw thenotch r out of alinement with the lug 8. When the device in this form isto act as a-guard to hold the door partly open the bar a is placedbehind the arm j'between the upper edge of the hook z and the projectionm. The stop it limits the distance the door can be opened, as beforedescribed, and the notch Z of the bar engages the upper edge of the hookz to prevent the door closing, when so held open.

' It will be observed that the movement of the bar a from the lockingposition, behind the hook z', to the guarding position, behind the armj, 1s direct, that is, the bar remainsin front of the door,substantially parallel therewith and giving full control over thedoor'movements when opened to be set and held ajar. This feature isparticularly prominent in the door fastener shown at Fig. 6; the bar 2'here being behind the arm 9' whenthe door is fully closed and locked andremains behind it when the door is openedto be placed on guard.

The movable member, hinged bar, of the device has heretofore beendescribed and shown as being attached to the j amb and the g othermember attached to the door; this, by

the nature of the invention, will of course be the general applicationof the device, as doors, by a very large majority, open 1nwardly, butwhen it is desired to apply the device to a door opening outwardly,then, without callingfor any change in the construction of the device,the movable member will be attached to the door and the fixed memberattached to the jamb.

I claim as my invention V 1. In a door fastener, a bar secured at oneend of the door jamb by a hinge connection, an upwardly extending hookor catch attached to the door and adapted to receive the bar when thedooris closed to lock the d,oor,,and means above the hook or catchadapted to receive the bar when it is raised free of hook or catch tohold the door partly open.

:2. In a door fastener, a bar secured at one end to the door jamb by ahinge connection, an upwardly extending hook or catch attached to thedoor and adapted to receive the 'bar when the door is closed to 'lockthe door, a guard arm above the hook or catch for receiving the bar whenraised out of the hook or catch and in which the bar slides when thedoor is opened, and a stop on the bar for limiting the, openlng movementof the door.

7. A door fastener comprising a bar having a hinge connection at oneend, a hook or catch adapted to receive the bar When the door is closed,to lock the door, a guard arm included in a plane, substantiallyparallel to the door, including the hook or catch, and adapted toreceive the bar when it is moved in said plane from behind the hook andto permit the bar to slide in it When the door is opened, said bar thenassuming an angular position to the door, and provision for preventingthe disengagement of the bar from the guard arm When in said angularposition.

8. A door fastener, comprising a bar having an enlargement or head atone end, a socket piece adapted to be attached to a door jamb and havinga recess for reception of the head of the bar and a slot in its facethrough Which the bar extends, constructed to provide a swiveling and alongitudinal movement of the bar, and a holding member adapted to beattached to the door having an upwardly extending hook behind Which thebar may be placed to hold the door closed, said bar then beingsubstantially parallel to the door, and a guard arm behind Which thebar, When moved in the plane parallel to the door and free of the hook,may be placed to hold the door partly open, a notch on the bar, and alug on the door member over Which the notch of the bar is passed Whenthe bar is longitudinally set to release the bar from the door member.
